Reducing RF Gain2 causes more
frequent AC application when the peak resolution is increased.
Normally, the
initial value of 60 is left unchanged.
3.2 MZ AC0, AC Gain
AC must be applied linearly according to the mass number.
The MZ AC0
parameter sets the mass number at which AC application starts at FWHM = 0.6.
AC Gain is the gain parameter for AC.

Linear AC application is inadequate in the medium mass-number range when AC
is first applied.
These parameters correct for this effect.
This correction is conducted from the mass number indicated for MZ AC0 up to the
value of AC1.
The mass number at which AC becomes AC1 is displayed as MZ
AC1.
AC Coeff and RES Coeff represent 100 times the order of the AC correction curve.

4.1 Checking the high mass-number range (414, 502, 614)
The high mass-number range is adjusted using MZ AC0 and AC Gain parameters.
With insufficient AC, peak separation deteriorates and the Valley value increases,
as shown in Fig. 4-1.
Increase AC Gain to increase the amount of AC applied.
With excess AC, as shown in Fig. 4-2, the peak separation is good but the signal
strength (sensitivity) deteriorates.
In this case, decrease AC Gain as much as
possible without decreasing the peak separation.

Fig. 4-4 Appropriate AC
Fig. 4-5
Excess AC
At m/z 219 and 169, the peak separation of isotopes deteriorates with insufficient AC,
as shown in Fig. 4-3.
With excess AC, a ridge appears before the peak, as shown
in Fig. 4-5, and signal strength (sensitivity) deteriorates.
If the m/z169 peak width
(FWHM) becomes too small, adjust it by decreasing RES Coeff.
The peaks appear as shown in Fig. 4-4 when the AC1, AC Coeff, and RES Gain
parameters are adjusted correctly.
5. When the checks are complete, confirm that FWHM lies in the range 0.6 ±0.05AMU.

Problems when turning the power on
1. MS does not turn on
Check the power supply.
□ Is the power supply voltage within the required range for the MS?
MS required voltage: 100V C 10%
□ Is the power cable connected correctly?
□ Is the wiring correct?
Check the power switch.
□ The power switch is on the instrument rear panel.
Is it in the ON (1) position?
Hint
The power supply switch incorporates a no-fuse breaker (NFB) function.
The breaker is operating if the switch returns after being turned on (but it does not
return fully).
This indicates a problem in the power line of the MS main power unit.
−−>See section 4.4 Main Power Assy.
Check the Status LEDs.
□ Is the POWER LED lit yellow?
−−> If not, see section 4.4 Main Power Assy.
Check the operation noise.
□ Can the fan be heard?
−−> If not, see section 4.4 Main Power Assy.
54
Problems when turning the power on
2. Abnormal Status LEDs
Check the status of the LEDs when the power is turned on.
□ Do the POWER (yellow) and FAILURE (red) LEDs remain lit?
−−> CPU is not operational.
Check the CPU-A power supply.
Hint
This symptom appears in the following circumstances:
No 24V supply to the DC POWER PCB.
(Check cables, connectors, MAIN POWER
PCB.)
No C15V supply to the CPU PCB.
(Check CPU PCB voltage, cables, DC POWER
PCB.)
No C5V supply to the CPU PCB. (Check CPU PCB voltage, cables, DC POWER
PCB.)
□ Do the POWER (yellow), READY (green), and FAILURE (red) LEDs remain lit?
−−> Defective DRAM operation on CPU-A.
Replace CPU-A.
□ Yellow, green, and red change to yellow and red, but red remains lit?
−−> Defective FPGA operation on CPU-A.
Replace CPU-A.
Hint
The CPU-A runs a self-test when the power is turned on.
The normal MS startup process
is shown below.
c Power on
d Yellow, green, and red light
(Green does not light if CPU is inoperative.)
e Yellow and red light (DRAM check OK.)
f Yellow lights (FPGA check OK.)
55
Problems when running software
3. Cannot connect to MS
Check the MS power supply.
□ Is the power switch turned ON (1)?
Hint
Connection with the PC is not established for about 15 seconds after the MS power is
turned on.
Wait for a while after turning on the MS for it to connect to the PC.
Check the connector cable.
□ Are the MS and PC connected correctly?
The MS and PC are connected together with an IEEE-1394 cable.
Check the device driver.
□ Is the device driver registered in the Device Manager?
See section 4.10 PCB Assy, CPU-A for details about how to check this.
56
Problems when running software
4. Cannot connect to GC
Check the GC power supply.
□ Is the GC power switch turned ON (1) ?
Check the connector cable.
□ Are the MS and GC connected correctly?
The MS and GC are connected together with a 232C cable.
Check the GC communications parameters.
□ Are the communications parameters set correctly?
The correct settings are LEVEL 3 and 57600.
Check the contents of the MS E2PROM.
□ Are the E2PROM contents set correctly?
The correct settings are LEVEL 3 and 57600.
The E2PROM contents can be checked by running MS2010.EXE.
57
Problems when starting evacuation
5. No ready status after automatic start
Check the GC settings.
□ Is an appropriate carrier gas pressure set at the GC?
An inappropriate carrier gas supply can result in no pressure increase at the column
inlet, so that the automatic startup sequence does not begin (and the rotary pump
does not operate).
Check that the set carrier gas conditions are suitable for the
column.
Check the rotary pump.
□ Is the rotary pump rotating?
If not, check the wiring.
If the wiring is correct, see section 4.4 Main Power Assy.
Check for leaks.
□ Is the unit front door completely closed?
Occasionally, dust can cause minute leaks.
Check that no dust is sticking to the
O-ring contact faces before closing the front door.
□ Is there any leakage from the interface column connector?
Leakage can occur from the interface unit after repeated analysis with heating.
Tighten the connector slightly (about 1/6 turn).
Caution: Fully tightening the connector with the wrench supplied could damage the
screw threads.
If slight re-tightening does not stop the leakage, replace the ferrule.
□ Is the column broken?
It is impossible to maintain a vacuum if the column breaks near the interface unit. If
the column is scratched during maintenance, it tends to break at the scratch.
□ If the analysis tube was opened during maintenance, is there any leakage from it?
If a normal vacuum could be maintained before maintenance but not after it, initially
check the positions where maintenance work were conducted and the interface
column connector (the temperature has been dropped).
58
Hint
It is sometimes possible to identify very large leaks by turning off the GC and MS and
listening for them.
59
Problems when starting evacuation
5. No ready status after automatic start (cont.)
Check PG.
□ Does the PG value fluctuate?
The turbo molecular pump (TMP) does start above 300kPa.
If no leaks exist, the PG could be defective.
See section 4.6 PCB Assy, Main
CTRL-A.
A discontinuity in the PG wiring causes an error message to be display and prevents
startup.
Check the TMP.
□ Is the TMP running?
A problem could exist in the MAIN POWER PCB or cable if the TMP does not run
although PG is less than 300Pa.
−−> See section 4.4 Main Power Assy.
□ Has a TMP power supply error occurred?
The status LEDs can be seen by removing the sheet metal between the GC and MS.
If an error is displayed for TMP power supply, this indicates a problem with the TMP
or TMP power supply.
Replace one of these and check the condition again.
Caution
The power supplies for the large TMP and small TMP are incompatible in early
GCMS-QP2010 models.
Never swap the wiring for testing purposes or normal
operation will not be subsequently possible.
Hint

Within warranty period: Contact the Quality Assurance Department or TS.
Outside warranty period: Repaired by service company (at a fee).
61
Problems when starting evacuation
6. Pirani gauge, IC value too high, IG does not light
Check the column flow rate.
□ Is the column flow rate within the recommended range?
At a column flow rate of approximately 2mL/minute, the Pirani gauge value is about
40Pa or lower at the start of evacuation and about 1 to 10Pa after one day.
The normal IG gauge value after one day is no more than 1 to 2E-3Pa.
(See Appendix E in the System User Guide.)
Check the N2 (m/z28) and O2 (m/z32) values.
□ If these values are larger than the m/z18 value
Check for looseness in the column connector and for damage to the input septum or
column.
Check the carrier gas piping.
Thoroughly purge the piping when GC/MS has been newly installed.
(After purging at the GC connector for several minutes, turn on the GC power, set the
purge flow and total flow to maximum, and leave for 10 or 20 minutes.)
Follow the vacuum-leak check procedures in the System User Guide to identify
vacuum leak positions.
Check IG.
□ Is the IG filament burned out?
An error is displayed if the IG filament is burned out.
□ Is the connector wired correctly?
Refer to sections 4.6 PCB Assy, MAIN CTRL-A and 4.9 PCB Assy, IC CTRL-A when
checking the IG control.
62
Problems when starting evacuation
7. Loud noise
Check the source of the noise.
□ Source is RP?
Oil deteriorated, worn rotor −> Replace oil, overhaul
□ Source is TMP1?
Defective bearing, wear, damaged blades −−> Replace TMP.
□ Source is TMP2?
Defective bearing, wear, damaged blades −−> Replace TMP.
Hint
To determine between a noise source in TMP1 and TMP2, turn on just one of them.
A tool program is needed to turn the turbo molecular pumps on and off individually.
63
Problems during tuning
8. No peaks obtained (peaks extremely small)
Check the tuning file.
□ Are the lens voltage values appropriate?
Revert the lens voltages to the default values if unclear whether the tuning values are
appropriate.
The default values are as follows:
L1 1.0V / L2 -20V / L3 -1.5V / L4 -40V / P-Rod -3.5V / M-Rod -3.5V / FIL-EV -70V /

4. MAIN POWER ASSY
Outline
The MAIN POWER ASSY uses switching power supplies to convert the supply voltage (100
to 240VAC) into the various supply voltages: DC POWER-A (±24V), IG CTRL-A (+5V), and
IS CTRL-A (+5V).
It incorporates a PCB that provides ON/OFF control of the rotary pumps
and turbo molecular pumps.
Operation Check Method
If an abnormality occurs, follow the procedure below to check the operation of the MAIN
POWER ASSY to efficiently diagnose the problem.
Caution
A voltage of 100 to 240VAC is supplied to the MAIN POWER ASSY.
To avoid electric
shocks or damage to the assembly, touch only the points instructed.
1. Checking the supply voltage
First, check that the power switch is in the OFF position.
Disconnect the MAIN POWER
ASSY cable connectors (Connectors c to j in the diagram) from the boards supplied or
from MAIN POWER.
Turn ON the power switch and measure the voltage at each
connector on the power line, as follows:
TMP1: Measure the voltage at Pin 1 of Connector c in the block diagram, relative to Pin 2.
(normal range: +22.7 to +25.3VDC)
TMP2: Measure the voltage at Pin 1 of Connector d in the block diagram, relative to Pin 2.
(normal range: +22.7 to +25.3VDC)
IS CTRL-A: Measure the voltage at Pin 3 of Connector e in the block diagram, relative to
Pin 1.
(normal range: +4.8 to +5.3VDC)
IG CTRL-A: Measure the voltage at Pin 3 of Connector f in the block diagram, relative to
Pin 1.
(normal range: +4.8 to +5.3VDC)
DC POWER-A: Measure the voltage at Pin 1 of Connector g in the block diagram, relative
to Pin 3.
(normal range: +22.7 to +25.3VDC)
74
Measure the voltage at Pin 5 of Connector g in the block diagram, relative to Pin 3.
(normal range: -22.7 to -25.3VDC)
If any abnormality is discovered in these voltages, check the switching power supply and
check the conductivity of the cable connections.
2. Checking the rotary pump (RP) ON/OFF control
Check RP1 and RP2 control using GCMSsolution.
Stop RP1 and RP2 using GCMSsolution.
the rear of the GCMS-QP2010.
Disconnect the RP1 cable and RP2 cable from
Measure the AC voltage across L and N of the RP1 outlet
at the rear of the GCMS-QP2010 to confirm that the voltage is 0V. Then, turn on RP1 and
again measure the voltage across L and N of the RP1 outlet to confirm that it is equal to the
instrument supply voltage.
Next, check RP2.
Measure the resistance across Pins 1 and 2 of the RP2 outlet to confirm
that they are insulated. Then, turn on RP2 and measure the resistance again to confirm
that the resistance does not exceed 5Ω.
If any abnormality is discovered in these checks and the MAIN POWER ASSY wiring is
normal, replace PUMP CTRL-A (225-11350-91).
3. Checking turbo molecular pump (TMP) ON/OFF control and the READY signal
Check TMP1 and TMP2 control using GCMSsolution.
Stop the evacuation system, disconnect connectors h and i from TURBO DRIVE.S
(TW300) and TURBO DRIVE.S (TW70H), and conduct automatic startup.
GCMSsolution that TMP 1 and TMP2 are on.
Check with
Measure the resistance across Pins 1 and 2
of the Connectors h and i outlet to confirm that the resistance does not exceed 10Ω.
A
resistance greater than 10Ω suggests a problem in a cable or in the PUMP-CTRL PCB
(225-11350-91).
Turn off TMP 1 and TMP2 using GCMSsolution and re-connect the connectors to their
correct positions.
Now, turn on TMP 1 and TMP2 again using GCMSsolution and confirm
that the TURBO DRIVE.S green READY LED light continuously. (Flashing indicates not
ready.)
The TURBO DRIVE.S green READY LED lit continuously but the GCMSsolution
indicating TURBO PUMP is NOT-READY suggests a problem in a cable (h, i, j) or in the
PUMP-CTRL PCB (225-11350-91).

5. DC POWER-A
Outline
DC POWER-A generates DC voltages for supply to CPU-A, PRE AMP-A, MAIN CTRL-A, IS
CTRL-A, RF GENE-A and DI CTRL-A.
Operation Check Method
If an abnormality occurs, follow the procedures below to check the operation of the DC
POWER-A PCB to efficiently diagnose the problem.
Caution
A voltage of 500VAC is supplied to the PCB.
To avoid electric shocks or damage to
the assembly, touch only the points instructed.
1. Checking the voltage supplied by the MAIN POWER ASSY
Check the voltages supplied by the MAIN POWER ASSY. The voltages are as follows,
when the chassis is grounded:
CP12 +24V (normal range: +22.7 to +25.3VDC)
CP14 -24V (normal range: -22.7 to -25.3VDC)
Abnormal supply voltages are probably due to a defective MAIN POWER ASSY.
Check
the MAIN POWER ASSY.
2. Checking the voltages generated by DC POWER-A.
The voltages are as follows, when the chassis is grounded:
CP1 -500V (normal range: -510 to -580VDC)
CP3 +500V (normal range: +510 to +580VDC)
CP4 +15V (normal range: +14.25 to +15.75VDC)
CP6 -15V (normal range: -14.25 to -15.75VDC)
CP7 +5V (normal range: +4.8 to +5.3VDC)
CP9 +60V (normal range: +57 to +68VDC)
CP11 -60V (normal range: -57 to -68VDC)
If the voltages above are not output, disconnect the connectors from J2 to J5, and repeat the
77
voltage check. If the output voltages are still not normal, the DC POWER PCB is probably
defective. Replace the DC POWER PCB. Conversely, if the voltages become correct
after the connectors are disconnected, the problem is probably in the cable supplying the
voltage or in the PCB receiving the voltage supply.

6. PCB ASSY, MAIN CTRL-A
Outline
MAIN CTRL-A generates the lens voltages, controls the solenoid valves, controls the
high-voltage supply, measures the vacuum with the Pirani gauge, and provides voltage
amplification functions for vacuum measurement using IG. It also functions as a relay
board between CPU-A and IS CTRL-A and DI CTRL-A.
Operation Check Method
If an abnormality occurs, follow the procedures below to check the operation of the MAIN
CTRL-A PCB to efficiently diagnose the problem.
Peak abnormality: Checks 1, 2, 3
Vacuum abnormality: 1, 4, 5
Caution
A voltage of C60VDC is supplied to the PCB. To avoid electric shocks or damage to
the assembly, touch only the points instructed.
1. Checking the supply voltages
Check the supply voltages.
The supply voltages are as follows, when the chassis is
grounded:
CP10 +15V (normal range: +14.25 to +15.75VDC)
CP13 -15V (normal range: -14.25 to -15.75VDC)
CP14 +24V (normal range: +22.7 to +25.3VDC)
CP29 +60V (normal range: +57 to +68VDC)
CP32 -60V (normal range: -57 to -68VDC)
2. Checking the lens voltages
Set the lens voltages with the Peak Monitor and confirm the output voltages at the check pin.
The normal output voltage lies in the range: set voltage ±5%.
CP16 LENS1 output voltage
CP30 LENS 2 output voltage
CP18 LENS 3 output voltage
CP31 LENS 4 output voltage
80
If the output voltages differ from the set voltages, check if the D/A voltages supplied from the
CPU PCB are correct.
CP23 = set voltage/1.5
CP26 = set voltage/5
CP24 = set voltage/1.5
CP25 = set voltage/5
Abnormal D/A voltages suggest a defective CPU PCB.
If the D/A voltages are normal but the output voltages are incorrect, conduct the following
checks to determine if the problem is caused by an abnormality in the lens voltage
generation circuits or by an abnormality in the vacuum vessel.
Turn off the power and disconnect the MAIN CTRL-A connector J8 to break the connection
with IS CTRL-A. Turn the power back on and repeat the lens output voltage check.
If the lens output voltages differ from the set voltages, the lens voltage generation circuits
are defective and the MAIN CTRL-A PCB should be replaced.
If the lens output voltages are the same as the set voltages, the lens wiring is probably
touching the inside of the vacuum vessel.
Open the door and check.
3. Checking the high-voltage power supply control circuits
EM HV circuits (-0.5 to -3kV)
Set the detector voltage and check the voltages at both CP4[V-EM] and CP2[FB-EM].
VCP4 should be 3 x detector voltage setting (kV). Any abnormality in this voltage is probably
due to incorrect D/A voltage from the CPU PCB.
Check that when EM HV is ON, VCP2=VCP4; when EM HV is OFF, VCP2・≒ 0V.
If the VCP2 voltage is generated whether EM HV is ON or OFF, this suggests a defective
controller operational amplifier.
Replace the MAIN CTRL PCB.
If VCP2 = 0V when EM HV is ON, the problem is probably in the high-voltage power supply
assy, or in the connector cables.
CD HV circuits (-1kV to -10kV power supply)
Check the mode.
The D9 photodiode lights green in the EI mode.
If the D9 photodiode lights red or does not light, the MAIN CTRL-A PCB is probably
defective.
Check the voltages.
Set the conversion dynode voltage and check the voltages at both CP3[V-CD] and
CP1[FB-CD].
81
VCP3 should be 1 x conversion dynode setting (kV). Any abnormality in this voltage is
probably due to incorrect D/A voltage from the CPU PCB.
Check that when CD HV is ON, VCP3=VCP1; when CD HV is OFF, VCP1 ≒ 0V.
If the VCP1 voltage is generated whether CD HV is ON or OFF, this suggests a defective
controller operational amplifier.
Replace the MAIN CTRL PCB.
If VCP1 = 0V when CD HV is ON, the problem is probably in the high-voltage power supply
assy, or in the connector cables.
82
4. Checking the Pirani gauge measurement control circuits
Check the operational amplifier power supply voltage.
CP9 +5V
Confirm that circuit output voltage is in the correct range.
CP8 0.47 to 2.84V (1 to 300Pa)
CP8 0.07V max.
(Voltage decreases as the pressure increases.)
Discontinuity in Pirani gauge.
Check the Pirani gauge resistance.
Disconnect the Pirani gauge cable from the MAIN CTRL-A PCB connector J5 and measure
the resistance between Pins 1 and 2.
The normal resistance is 10 to 15Ω.
5. Checking the ion-gauge vacuum measurement circuit
If measurements seem incorrect, check the output from the ion-gauge collector current
amplifier circuit.
CP6 [IG1]
A degree of vacuum in the range 1.3x10-3 to1.3x10-1Pa is determined from the voltage VCP6.
Degree of vacuum (Pa) = 3.33x10-2 x VCP6
When the degree of vacuum exceeds 1.3x10-1Pa (VCP6≥4V), the filament is turned off for
protection.
CP7 [IG100]
A degree of vacuum below 1.3x10-3Pa is determined from the voltage VCP7.
Degree of vacuum (Pa) = 3.28x10-4 x VCP7
A discontinuity in the ion-gauge measurement bulb or connection cable is evaluated if VCP7
is 0.1V or less, and the ion-gauge filament is turned off.
Inspect the cable between the
measurement bulb and connector J4 on the MAIN CTRL-A PCB.
Check the ion-gauge control circuit (IG CTRL-A) if the ion-gauge measurement bulb filament
does not light.

7. IS CTRL-A ASSY
Outline
IS CTRL-A provides functions for filament control and ion-source temperature control. It
also functions as a relay board to introduce the lens voltages sent from MAIN CTRL-A into
the vacuum vessel.
Filament control (EI mode)
If one filament is selected, the other filament can be used as a trap electrode.
The filament
potential (emission voltage) and the amount of thermoelectrons emitted from the filament
(emission current) are set using D/A. When the filament is turned on, current flows into the
filament, causing the emission of thermoelectrons.
A proportion of these reach the trap
electrode that is held at a potential of +10V, and are measured as the trap current.
An error
amplifier operates to control the filament current to maintain the trap current equal to the set
emission current value.
Ion-source temperature control adjustment
The voltage applied to the heater is proportional to the duty ratio of the PWM waveform
generated by the CPU. A platinum (Pt) sensor measures the temperature.
Operation Check Method
If an abnormality occurs, follow the procedures below to check the operation of the IS
CTRL-A PCB to efficiently diagnose the problem.
Signal peak abnormality: Checks 1, 2, 3, 4, 5
Ion-source temperature abnormality: Checks 1, 6, 7
Caution
A voltage of -200VDC is supplied to the PCB.
To avoid electric shocks or damage to
the assembly, touch only the points instructed.
1. Checking the supply voltages
CP3 +15V (normal range: +14.25 to +15.75VDC)
CP5 -15V (normal range: -14.25 to -15.75VDC)
CP9 +24V (normal range: +22.7 to +25.3VDC)
When CP6 is measured with respect CP7: +5V (normal range: +4.9 to +5.3V when filament
is off)
2. Checking the lens voltages
86
Set the lens voltages with the Peak Monitor and confirm the output voltages at the
feedthrough contacts on the IS CTRL-A PCB.
The normal output voltage lies in the range: set voltage ±5%.
LENS1, LENS2, LENS3, LENS4
If the output voltages do not lie within the set ranges, conduct the checks described in 2.
Checking the lens voltages for MAIN CTRL-A (page 60).
3. Checking the filament currents
When a filament is on, the filament current can be determined from the following voltage
measurements. The relationship between the filament current and the voltage measured
with the tester + probe on CP16[FIL] and the - probe on CP18[EV] is as follows:
Filament current (A) = 2 x (VCP16 – VCP18)
max about 3.5A
If (VCP16 – VCP18) = 1.4V, the filament current is 2.8A.
A filament discontinuity is detected and an error occurs if (VCP16 – VCP18)≤approx. 0.6V, that
is if the filament current ≤approx. 1.2A.
The discontinuity in the filament can be easily confirmed by the following method.
Turn off the filament and measure the resistance between F1+ and F1-.
If resistance value ≤1Ω, the filament is normal.
Be aware of the polarity when measuring the resistance; correct measurement is only
possible by applying a positive voltage to F1+ and a negative voltage to F1-.
If the polarity
is unknown, turn off the instrument power, remove IS CTRL-A to eliminate the influence of its
circuits and measure the resistance directly at the feedthrough terminals.
4. Checking the TRAP current control circuit
Set the emission current, turn the filament on, and measure the voltages at CP12[EMC],
CP13[TRP], and CP14[+10A].
If VCP14≠10V, the IS CTRL-A PCB is probably defective.
VCP12=set current(µA)/100
If emission current = 60µA, VCP12=0.6V.
Any abnormality suggests an incorrect D/A voltage from the CPU PCB.
VCP12=VCP13
Any abnormality could be due to a filament discontinuity or incorrect installation.
5. Checking the emission voltage control circuit
This circuit generates the emission voltage (-10V to -200V).
Set the emission voltage, turn the filament on, and measure the voltages at CP15[EMV],
CP18[EV], and CP19[INV].
VCP15= 0.05 x set voltage (V)
If emission voltage = -70V, VCP15=-3.5V.
87
Any abnormality suggests an incorrect D/A voltage from the CPU PCB.
VCP18= set voltage (V)
A voltage in the range set voltage ±10% is normal.
If abnormal, check the voltage VCP19.
If VCP19 is not in the range +1 to +15V, the IS CTRL PCB is probably defective.
If the VCP19 voltage is in the normal range but VCP18 ≠set voltage, the filament wiring is
probably touching another electrode inside the vacuum vessel.
6. Checking the heater circuit
The ion-source heater operates on 24VDC.
No temperature rise when the ion-source temperature is set and the heater should be
operating could be due to a heater discontinuity, short-circuit, disconnected wiring, or
incorrectly installed heater temperature sensor.
Follow the procedure below to diagnose
problems with the heater.
Check that the CP2 voltage = +19±1V.
If abnormal, replace IS CTRL-A.
Measure the voltage applied to the heater at the feedthrough contacts on the IS CTRL-A
PCB.
HT+
HT-
Heater + voltage (0 to +24V)
Approximately 24V during heating.
Heater - voltage (0V)
The IS CTRL-A PCB is normal if a voltage is applied to HT+.
If the voltage at HT is approximately 0V, a short-circuit has probably occurred in the vacuum
vessel.
Turn off the heater with the tool program. (The sound of the relay on IS CTRL-A operating
should be audible.)
Check that the voltage at HT+ is 0V, and then measure the resistance
across HT+ and HT- using the tester resistance mode.
A resistance of 15 to 25Ω is normal. Be aware of the polarity when measuring the
resistance; correct measurement is only possible by applying a positive voltage to HT+ and
a negative voltage to HT-.
If the polarity is unknown, turn off the instrument power, remove
IS CTRL-A to eliminate the influence of its circuits and measure the resistance directly at the
feedthrough terminals.
Observe the CP1[PWM] waveform with an oscilloscope.
This is normal if an ON/OFF PWM waveform between 19 and 24V is observed, and the HT+
output voltage is approximately proportional to the duty ratio of the PWM waveform (0 to
100%: 0 to 24V).
An abnormal PWM waveform suggests a defective CPU PCB or MAIN CTRL-A PCB.
7. Checking the ion-source temperature measurement circuit
88
The temperature sensor is a platinum (Pt) sensor.
Check the voltage at CP8[TEMP].
VCP8≥4V suggests a discontinuity in the platinum sensor or its wiring.
VCP8≒0V suggests a short-circuit in the platinum sensor or its wiring.
The resistance of the platinum sensor varies approximately linearly from 100 to 250Ω in the
temperature range from 0 to 400MC.
Approximate expressions : RPt(Ω) = 0.37 x T (MC) + 100
VCP8 = 15 x RPt /(1000+RPt)
Any large discrepancy from these relationships suggests an abnormality in the temperature
measurement circuit.
Replace IS CTRL-A.

Action confirmation method
If an abnormality occurs, follow the procedures below to check the operation of the HV
PCB ASSY to efficiently diagnose the problem.
Please refer to even the item of "the confirmation of
MAIN CTRL-A high pressure power
supply control circuit".
CAUTION！
The voltage on a foundation becomes biggest 10kV with DC. Please do not touch on
unpreparedness, Because of the damage prevention of electric shock prevention,
measurement devices.
Please turn off the power supply when I remove a foundation.
Next, please
discharge the remaining electric charge of a high voltage terminal in body with an
electric wire and driver etc.
And, please do so that it touches.
１．Confirmation of the electric discharge by insulation defectiveness
Please turn off EM and CD On a service program.
And, please confirm the presence of the sound by an electric discharge.
It is thought as the insulation defectiveness of HV PCB ASSY, when it is heard as the sound
that discharges is occurring outside a vacuum vessel.
91
In this case、You had better
exchange this part.
Please confirm the following, at the time of such that an electric discharge is occurring in a
vacuum vessel.
Please suspend a device.
You had better confirm whether dust is not adhering, whether or
not wiring is appropriate after takes out a detection device unit.

２．Confirmation of the wiring within a vacuum vessel
Please confirm whether or not, the output of the high voltage power supply is out with the
next method.
You monitor the base line of the condition of filament off with a service program.
Please turn on only EM.
EM is normal if the base line is goes up a moment.
Please turn on only a CD.

mode (-1kV〜-10kV) ,the CD is normal.
If the base line descends a moment conversely in a NCI mode (+1kV〜+10kV),
The CD
is normal.
When the base line does not fluctuate normally 、it stops the device and take out the
detection device unit and confirm please whether wiring is not coming off.

is thought about whether someday.
The short circuit of the wiring inside a vacuum vessel is conceivable as the cause of
defectiveness.
Or, it is conceivable as the cause of the defectiveness of HV PCB ASSY.
Besides, it is conceivable as the cause of the defectiveness of MAIN CTRL-A.

9. PCB ASSY, IG CTRL-A
Outline
IG CTRL-A lights the ion-gauge measurement bulb (IG bulb) filament and generates the grid
voltages.
The MAIN CTRL-A PCB offers the functions to measure the collector current to
determine the degree of vacuum.
When the filament lights, thermoelectrons are
discharged toward a grid held at a potential of +150V, resulting in a current from the grid to
the filament (grid current).
As the filament is lit by a power supply with a floating potential,
the grid current flows toward earth potential in the IG CTRL-A circuit.
This circuit adjusts
the current flowing through the filament to maintain a 1mA grid current flow to earth potential.
The grid current flows through a Zener diode, which increases the filament potential above
earth potential by the amount (Zener voltage + voltage drop in the current detector
resistance), giving a potential of +25V at a 1mA grid current.
The degree of vacuum is
determined from the amount of positive ions captured at the earth-potential collector
electrode.
Operation Check Method
If an abnormality occurs, follow the procedures below to check the operation of the IG
CTRL-A PCB to efficiently diagnose the problem.
In case of abnormal degree of vacuum measured values, see the item Checking the
ion-gauge vacuum measurement circuit for the MAIN CTRL-A PCB (page 62).
Caution
A voltage over +150VDC is supplied to the PCB.
To avoid electric shocks or damage
to the assembly, touch only the points instructed.
1. Checking the installation
One of the four screws locating the IG CTRL-A PCB acts to earth the PCB to the chassis.
Current flows may be interrupted if this screw is loose.
Be sure to correctly tighten these
screws.
Check there is no looseness in the connector socket contacts where the IG bulb pins are
inserted.
95
2. Checking the voltages
Measure the voltage with the tester + probe on CP1[F+5VIG] and the - probe on
CP2[F0VIG].
The normal voltage range when IG is off is +4.9 to +5.3V.
drops slightly when IG turns on.

3. Checking the grid and filament voltages
Turn IG on with the tool program and measure the grid and filament voltages (CP4[GRID],
CP5[FIL-], CP3[FIL+]). These voltages can also be measured at the IC bulb connector.
Check the grid.
Voltage across CP4[GRID] and IG bulb, Pin 4 = 15010±V
Pull out the IG connector if VCP4 is abnormal.
If VCP4 becomes normal, replace the IG bulb.
If the voltage remains abnormal after the connector is disconnected, replace the IG CTRL-A
PCB.
Check the filament.
If the filament does not light, turn IG off and measure the resistance between Pin 3 and Pin 5
of the IG bulb.
The resistance should not exceed 1Ω.
Replace the IG bulb if the
resistance is abnormal.
If the filament does light:
Voltage across CP5[FIL-] and IG bulb, Pin 5 = 251±V
An abnormal VCP5 value indicates an abnormal grid current. Replace the IG CTRL-A PCB.
If the filament is normal : Filament voltage (VCP3 – VCP5) = 3.0 to 4.0V

11. RF PS ASSY
Outline
The RF PS ASSY generates the high frequencies applied to the main rod and pre-rod.
As shown in the block diagram, the main rod comprises a pair of opposing poles maintained
at the same potential, to which the following voltages are applied:
A pole = high-frequency (V) + DC voltage (U) + AC voltage (AC) + bias voltage
B pole = high-frequency (-V) + DC voltage (-U) + AC voltage (-AC) + bias voltage
(Where high-frequency = 1.05MHz, AC=52.5kHz.)
Only the high-frequency and bias voltage are applied to the pre-rod.
Operation Check Method
If an abnormality occurs, follow the procedure below to check the operation of the RF PS
ASSY to efficiently diagnose the problem.
Caution
A ±2500V high-frequency voltage and±500VDC are supplied to the RF PS ASSY.
To avoid electric shocks or damage to the assembly, touch only the points instructed.
Caution! Static Electricity
The RF PS ASSY contains parts that are sensitive to electrostatic discharge (ESD).
Static electricity at 4000V or more can easily accumulate on the human body and be
discharged.
D3 to D6 on the RF GENE-A PCB can withstand only 10V static electricity.
Take the appropriate ESD countermeasures when replacing RF GENE-A.
1. Checking the supply voltages
Check the supply voltages.
The voltages should be as follows, when the chassis is
grounded.
CP1 +15V (normal range: +14.25 to +15.75VDC)
CP2 -15V (normal range: -14.25 to -15.75VDC)
CP3 +500V (normal range: +510 to +580VDC)
CP5 -500V (normal range: -510 to -580VDC)
102
CP6 -24V (normal range: -22.7 to -25.3VDC)
CP7 +24V (normal range: +22.7 to +25.3VDC)
CP12 +5V (normal range: +4.8 to +5.3VDC)
103
2. Checking the tuning
Use the tool software to check if the tuning is correct.
If tuning is correct (if the screen value valley can be confirmed by turning the core trimmer) it
is safe to judge that the circuits related to the RF power-supply high frequency (V) are
normal.
Conversely, if the tuning is not correct, the high-frequency-related circuits are defective or
the load is abnormal.
Check the wiring around the QP rod.
Explanation
When the RF value is set with the tool software, the set voltage is output from CP8[V-RF]
(approximately 4.58V at m/z500).
1.05MHz is output when the RF output turns on, and a sine wave is output from CP13 to
create a proportional relationship between the set value and high-frequency wave detection
feedback value CP4[FB].
If the proportional relationship is not maintained, output CP16
goes out of range and an error signal is output.
CP13 is connected to the primary side of the coil and outputs an approximately 50 to 70VP-P
sine wave at a setting of m/z500. The value monitored by the tool software is the value
read from CP14.
3. Checking the U voltage
If the check of the tuning indicated that the V voltage is correct, next check the U voltage.
When the main rod bias is set to m/z500 at -3.5V, check that the CP10[U1] and CP9[U2]
values are approximately 204V at the positive side and approximately -210V at the negative
side. It is recommended to use the Tuning Check window to make the RF setting (because
RF scanning is conducted from other windows). The RF setting changes due to switching
the positive and negative polarity (A or B) and due to the ionization mode (positive or
negative).
Explanation
As the U voltage is generated from a feedback output, if the U voltage is correct, then the V
voltage must also be correct.
(This provides reconfirmation.)
error signal if the U voltage is not output.
RF GENE-A outputs no
Consequently, the U voltage output should be
suspected if no peaks are obtained but the RF power supply outputs no error.
4. Adjusting the trimmers
104
If the checks above are all satisfactory but still no peaks are obtained, possibly the settings
of trimmers VR1 and VR2 are seriously wrong.
In this case, turn VR1 while monitoring the
low mass numbers m/z18 and m/z28 to obtain equal peak amplitudes.
If this adjustment is
not possible even by fully turning VR1, switch JP1 and attempt the adjustment again.
Repeat the adjustment with 1) JP1 unshorted, 2) 1 to 2 shorted, and 3) 2 to 3 shorted. If
equal peak amplitudes are achieved, conduct fine adjustment of the trimmers using the tool
software.
105
5. Checking the AC voltage
The AC voltage is normal if 2 to 3VP-P is output from CP15[AC] when m/z500 is set. (It
fluctuates due to AC adjustment.)
6. Checking the pre-rod bias
The pre-rod bias is normal if JT1[PRE] is within pre-rod bias set value ±10%.

2. Adjustment in the high mass-number range
This instrument incorporates an auto-tuning function that conducts mass-number calibration
at m/z614.
Mass-number displacement is rare in the normal range of operation (up to
approximately m/z700.)
However, displacement from the calibration at m/z is possible in the high mass-number
range.
Ensuring accurate calibration in the range m/z700 to m/z1000 requires manual calibration
by injecting a triazine (Tris(perfluoroheptyi)-S-triazine) high-mass-number standard sample
into the column.
Procedure
Instrument conditions
Sample: triazine 1% solution in acetone, ultrasonically mixed
INJ: 250MC
COL: 50MC (1 min.)-5MC /min-100 MC (1min)-30MC /min-250MC (10min)
I/F: 250MC
Ion source: 200MC
Column head pressure: 100kPa
Total flow rate: 30mL/minute
Splitless injection (1 min. sampling)
Triazine flow time is approximately 3 minutes between minute 11 and minute 15
c Take 1µL triazine sample into a syringe and inject it into INJ.
Wipe any sample from
the syringe tip before injecting the sample.
d Monitor m/z771, 886, and 1016 on the Peak Monitor window.
Leave the filament off
for the first five minutes after sample injection, turn the filament on, and wait for the
peaks to appear.
e The triazine peak can be seen for the three minutes between minute 11 and minute 15.
Check the mass number (within C0.3 mass) and resolution (FWHM resolution 0.1M
max.).
Conduct manual compensation, if necessary.
f After making this check, increase the column temperature to 250MC to drive out the
triazine. Ten minutes at 250MC is insufficient, conduct this process for 1 hour at
250MC.
Caution) Traces of the injected triazine may remain in the sample lines and
hinder subsequent analysis.
Allow the column to age overnight at
250MC before conducting ultramicroanalysis.
114
Degree of residue
After driving the triazine out of the column for one hour at 250MC, SCAN data
measurements (approx. 1ppm) can be conducted without hindrance.
Aging for 2 to 3 hours at 250MC is recommended for microanalysis (SIM
measurement 100ppb or below) but aging overnight is recommended for
ultramicroanalysis (10ppb or below).

4. Power requirements
Caution
Provide the instrument with a separate power supply protected by an earth
leakage breaker. It must not share a power supply with any other equipment.
Caution
To prevent electric shocks, connect to earth with a grounding resistance not
exceeding 100Ω.
Note
Although the instrument is designed to operate normally with ±10% AC line
voltage fluctuations, including accumulated rapid noise, to ensure performance
specifications are met, the voltage fluctuations (including noise) should not
exceed ±5%. The power supply equipment must be improved if the voltage
fluctuations exceed ±10%. Frequency fluctuations must not exceed ±0.5Hz.
The power supply requirements for each unit are listed below.

Cautions on handling high-pressure gas cylinders
The gas cylinders used are covered by the High-pressure Gas Safety Law.
Strictly follow the provisions of the High-pressure Gas Safety Law when handling
these cylinders.
General Precautions
1. Locate the cylinders in a well-ventilated position outside that is not subjected
to direct sunlight. Transfer the gas through pipes.
2. Do not allow the cylinder temperature to exceed 40MC. Allow no naked
flame within two meters of the cylinders.
3. Ensure sufficient ventilation where high-pressure gas is used. Check for gas
leaks with soapy water during the start-up inspection. If flammable gas
(such as methane) is used, allow no smoking or naked flame within a 5m
range. Provide effective fire extinguishers.
4. Fasten cylinders with chains to ensure they cannot fall over.
5. Use an oilless gas pressure reducer. Do not use pipe with oil on the internal
gas-contact surface.
6. Immediately close the cylinder valve when the gas is no longer required.
7. Legal permission is required to store gas quantities of 300m3, or more. Refer
to the High-pressure Gas Safety Law, General High-pressure Gas Safety
Regulations, and Fire Protection Law.
6. Exhaust
Provide exhaust duct plant and connect it to the instrument to prevent the discharge of
oil mist or injected solvents and sample directly into the room. (See the Exhaust Duct
Example below.)
As a guide, the exhaust duct plant should provide a flow of 3 to 20m3/minute. A
normal draft chamber can also be used.
The following oil-mist filter is available for use in situations where provision of an
exhaust duct is not possible. If this filter is used, injected solvents and samples are
discharged directly into the room.

#2 If carrier gas leaks or when glass insert is replaced.
#3 Replace periodically, normally once every 6 months.
However, replace more frequently under
certain measurement conditions or after many analyses of samples with a high boiling-point or
samples that are solid at room temperature.
(See GC System User Guide for details.)
#4 Use when column is replaced.

#1 Once every 3 years is sufficient, unless some unforeseen accident occurs.
This is an expensive part and having one available can avoid sudden expenditure. However, storage over a long period
is not recommended, as the detector deteriorates if unused for long periods.
#2 Overhaul required every 25,000 hours (approx. 2.8 years).
#3 Overhaul required every 15,000 hours (approx. 1.7 years).
